\begin{equation}  G_y = \frac{\cos \beta \sin \beta}{4\pi \rho c_p^2 r} \delta_P + \frac{-\sin \beta \cos \beta}{4\pi \rho c_s^2 r} \delta_S + \frac{3\cos \beta \sin \beta}{4\pi \rho r^3} \tau Rect\\  G_z %G_z  = \frac{\cos^2 \beta}{4\pi \rho c_p^2 r} \delta_P + \frac{\sin^2 \beta}{4\pi \rho c_s^2 r} \delta_S + \frac{3\cos^2 \beta-1}{4\pi \rho r^3} \tau Rect \\ \label{eq:akirichards}  \end{equation}  where $\beta$ is the angle between the applied force and the axis y or z, $\rho$ the medium density, $c_p$ and $c_s$ the compression and shear wave speed respectively, $\delta_S$ and $\delta_P$ Dirac distribution indicating the position of the compression and shear waves along space and time, $\tau$ the time and $Rect$ the near-field term. The three terms correspond respectively to the far-field compression wave, the far-field shear wave and the near-field term.
